Hi guys. First post, hope you can help. As above 1991 Honda fourtrax. Starting, running fine until a few weeks ago. Used primarily to put my ski boat in the garage (put 2" ball on front). Any way, had just backed boat into garage, turned off to crank trailer wheel down, when I went to restart got nothing.
No neutral light, no headlights, no reverse light, would not turn over when start button pushed. It would crank and run when I jumped the contacts on the start relay. While running the neutral light will come on, although it is dim and flickers. Reverse light on when running and in reverse.
What I have done to this point:
1. Used jumper cable to ground battery (-) terminal to engine block thinking ground wire from battery to engine may be bad. No neutral light, no start.
2. Applied 12 volts to start relay. Got a loud click like it was making contact. I didn't have the battery/starter cables connected to the relay, but I am assuming it would have cranked at that time.
3. Disconnected neutral switch wire. Grounded neutral switch wire with jumper wire. No neutral light, no electric start.
At this point I am thinking ignition switch vs broken wire in the harness going to the neutral switch (due to dimness and flickering when running).
Any and all suggestions to help track down this issue are appreciated.
My lakota has a new carb and just had a top end redone by a professional, but it will not start. The electric start turns it over great, there seems to be compression. It seems like its trying to start, getting right there and just doesnt catch. It does start occasionally, but wont run for more than a couple of minutes and smells rich. Im assuming the carb needs to be tuned, but im just wondering if anyone else has any ideas before i get a chance to work on it.

I picked up this quad after the previous owner couldn't get it going.
The issue is that I can't get it to fire at idle or at all.
- replaced plug. Decent blue spark. Also tested with spark tester inline.
- rebuilt the carb. PO had already bypassed vacuum lines from petcock. There's fuel at the cylinder
- Checked compression with new gauge. reads 190 psi
- cleaned all contacts I could access.
- am currently jumping with car battery. Solenoid jumpered.
- checked cam timing at TDC and adjusted valve lash
- put gas directly into cylinder to see if it will fire at least momentarily
Motor turns over well. Plug gets wet.
Motor may fire once or twice but smokes through exhaust a bit as if it's trying to fire or combusting.
This leads me to suspect timing. As mentioned I checked the flywheel mark versus cam marks. Perhaps someone has been in there before because I can't find a 'T' on the flywheel but there is a very visible paint mark which aligns with TDC position on piston. Possibly a slipped flywheel/woodruff?
Is it possible that if it had seen previous repairs, that the timing could still be off? I'm reluctant to dig into the flywheel/stator area if there's something else I could have missed but all signs point me to that area. Would a bad CDI cause spark timing to be off?
Anywhere else to diagnose incorrect spark timing?
I've scoured these forums and elsewhere but I'm posting just in case there's something I've overlooked up until now.
Thanks very much for reading!

So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
It will run and idle decent now but when I give it gas it dies.
Does anybody know what could be wrong?
I also changed the spark plug and air filter along with the oil and oil filter.
I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?
Hi, does anyone know where to find the timing marks on the camshaft and how to orient them? I found the line on the crank and lined it up with the arrow on the case, but the only marks I can see on the cam are on the very end where the black plastic cap is. Are these the timing marks and if so how do you line them up?
I went out to ride my quad today. When I started it up it ran for a minute, then died. Since then it will turn over but won't start. I've check the spark plug and get great fire. I have had this quad for about 6 months, and very new to breaking it down. But need help. Thanks
